Today we added a fresh piece of contact to explore the balloons.
We noticed when it inflated that they stuck to the wall. Once stuck to the wall we pulled them off or hit them off.
We then repeated the process of sticking it to the wall and pulling it off. We noticed that they come straight down when we throw them in the air.
We started to recognise that some balloons were smaller than others and the more air that they had, the less they stuck.
